An Abelian group is called quotient divisible if it does not contain nonzero torsion divisible subgroups, but does contain a free finite-rank subgroup such that the quotient group by it is divisible. In this paper, we will describe rank-1 quotient divisible groups with the help of cocharacteristics, and we will describe the endomorphisms of these groups as well.
